How to tell if eggs are spoiled How to tell if eggs are spoiled

Eggs are a kind of food that many people love to eat, but if eggs are not stored properly, they are very easy to spoil. Even if they are placed in the refrigerator, they will go bad. Therefore, you must understand the shelf life and storage temperature of eggs. Try not to place them in a place with a relatively high temperature, otherwise the chance of deterioration will be higher. Once you find that the eggs you bought have deteriorated, you should not eat them anymore.

1. Symptoms of egg spoilage

After opening the egg, if you find that the yolk is scattered, the egg white and yolk are mixed together, or there is a musty or rancid smell, you can no longer eat it. This is the most direct way to determine whether the egg has gone bad.

Use sunlight transmission: Hold the egg in a circle with your left hand, place the egg at the end of the circle, and transmit sunlight through it. Fresh eggs will appear slightly reddish and translucent, with a clear yolk outline. If the egg is dark, opaque, or has stains, it means it has gone bad.

Test with cold water: if the egg lies flat in the water, it means it is fresh; if it is tilted in the water, it has been stored for at least 3 to 5 days; if it stands upright in the water, it may have been stored for 10 days; if it floats on the water, the egg may have deteriorated.

Fresh eggs have a layer of white frost on their shells, and the shells are bright in color with obvious pores. Otherwise, they are stale eggs.

Gently shake the egg with your hand. If there is no sound, it is a fresh egg. If there is a sound of water, it is a stale egg.
